Characteristics:

• filter class G3 according to EN779 and ISO coarse 55% according to ISO 16890
  for filter fan / exhaust filter with a mounting cutout of 224 x 224 mm
• high performance nonwovens from elastic, break-resistant polyolefine fibers with thermal bonding
• progressive in structure, with layers being arranged behind each other so as to ensure that the density of the fiber layers increases towards the clean air side
• this optimizes the defined filter performance and the dust holding capacity, resulting in longer useful lifetime for the filter concerned (slow pollution and high durability)
• complete regenerative for several times by careful washing, beating or spraying (long lifetime)
• high mechanical strength of the material used offers good dimensional stability throughout the operational lifetime
• thanks to the polyolefine fibers used in the medium, the filter mats are widely resistant to chemicals like solvents, acids and alkalis
• fire behaviour: the filter mats satisfy the stringens requirements of fire class F1 according to DIN 53438 and are thus self-extinguishing
